Dear Anne - Thank you so much for your swift reply. I had a quick search through previous posts here, but perhaps with insufficient diligence… I did note the one you linked, but the solution ‘… System Variable JAVA_HOME set to a 32-bit java installation…’ was slightly beyond my technical grasp. Probably not with some input from google however…
Anyway, thanks for letting me know the issue is likely with java - I will investigate this and try to fix / will post back with an update.
Finally - a huge thank you for everything you and the CellProfiler team do to provide with accessible tools for bio image analysis. (I’m one of Paul’s minions btw! : ))
Best wishes - John
